552 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



shallow circular impressions, the apical largest, the basal without 

 a tongue, and not opening out to base. Ehjtra with all the 

 interstices punctate, the 2nd and 4th in two moderately distinct 

 rows, the suture in but one row, the 3rd raised and rounded, 

 towards apex becoming keel-like, the 5th and 7th keel-like and 

 with a narrow row of punctures on each side; stride narrow, the 

 lateral ories only visibly punctate. Under su7'face feebly longi- 

 tudinally punctate. Length 4, width li mm. 



Hah. — Gerald ton and Swan River, W. A. 



Differs from B. variabilis especiall}^ by the prothorax, which is 

 shorter, less coarsel}^ and differently punctured, the basal impres- 

 sion circular and without a tongue; the under surface is much 

 less coarsely punctate; but it may be most readily distinguished 

 by the 2nd elytral interstice being shining and with two rows of 

 punctures. 



BOTHRIDERES ABEERANS, n.sp. 



Red, elytra slightly opalescent. 



^earf densely punctate, punctures longitudinal; a rather distinct 

 impression on each side of clypeal suture. Prothorax slightly 

 transverse, apex ver}^ slightly wider than base ; convex ; very 

 densely but not coarsely punctate, with a small and very feeble 

 impression on each side of base, scarcely visible from most direc- 

 tions. Eh/tra convex, with suture raised and thickened, each 

 with four strongly raised keel-like ridges, one of which is lateral; 

 the interspaces very feebly and shallowly punctate and not at 

 all striate. Under surface, except prosternum and four apical 

 segments of abdomen, highly polished and almost impunctate. 

 Length 3, width 1 mm. 



//a6. — Tamworth, N.S.W. 



The convex prothorax entirely without discal impression, 

 strongly ridged, convex and non-striated elytra render this species 

 at once the most distinct and the most aberrant of the genus.
